In maintaining advantages in cotton breeding suitable to spinnin middle-count yarn, breeding research for cotton varieties suitable to spinning high-count yarn and middle-low-count yarn should be strengthened, and new varieties must be resistant to Fusarium and Verticillium wilt and cotton bollworm and must have high rate of cotton yield before frost, and emphasize the applicalion of transgenic breeding technique in future.

今后应在保持适纺中支纱棉花新品种选育优势的同时，加强适纺高支纱和中低支纱棉花新品种选育，育成品种必须抗枯、黄萎病，抗棉铃虫，霜前花率高，增强稳产性和适应性，并重视转基因育种技术的应用。

Compared with previous studies on old Chinese cultivars released or planted before, the frequencies of high breadmaking quality related subunits, such as subunit 1 and 5+10, together with allelic variations and subunit composition patterns, increased significantly, resulting Glu-1 quality score above seven.

与前人研究相比，新育成品种HMW-GS亚基组成发生了明显变化，面包优质亚基1、5+10出现的频率显著升高，亚基多态性增加，组成形式明显改善，这些对于品质改良和品种选育是非常有利的，新育成品种Glu-1品质评分已超过7。

Study on glutenin subunits,GMP content and their relationships with(T.aestivum L.)With the analysis of high and low glutenin subunits of common wheat(Triticum aestivum L.)in China,the correlations between glutenin compositions,glutenin macropolymercontentand breadmaking quality were studied.Also a rapid and efficient detection method of geneticpolymorphism at Glu-D1y loci in wheat was established using polymerase chain reaction.

分析了100份小麦农家品种和241份育成品种的高、低分子量谷蛋白亚基的组成以及有关的品质性状，研究了高分子量谷蛋白亚基频率的变化，用单向一步SDS-PAGE的方法分离LMW-GS，并对我国小麦品种进行初步分类；在亚基水平上研究了不同的亚基或亚基组合对品质性状的影响；在聚合体水平上研究了谷蛋白大聚合体的含量与其他烘烤品质性状的相关性及其在面包体积预测中所起的作用；在基因水平上利用PCR技术研究了1D染色体上控制y-型谷蛋白亚基的Glu-Dly位点基因的多态性。

Soybean is sensitive to flooding and waterlogging stress, especially at early seedling stage as well as flowering and podding stages; On the other hand, there existed great difference in the tolerance to flooding or waterlogging in soybean germplasm, so utilizing tolerant cultivars is one of the most effective ways to improve the soybean production under flooding and waterlogging stresses condition.

长江中下游地区常有梅雨天气，大豆苗期易形成涝害。在前人研究我国大豆资源耐淹性的基础上，本文进一步研究我国和亚洲其他国家大豆育成品种苗期耐淹性的遗传变异，发掘优异资源；对耐淹性进行关联定位，寻找优异等位变异及其载体材料，并追索在后代育成品种中的累积。

Breedings had a relatively smaller number of alleles and genetic diversity than landraces, but no significant differences abserved.

说明不同的连锁群其保守性不同。 3。微核心种质中育成品种与地方品种相比，等位基因数和基因多样性均略低。

Compared with modern cultivars and introduced accessions, greater genetic diversity was observed in landrace.

地方品种表现较高的遗传变异，而现代育成品种的遗传多样性比较低。

Cultivars and landraces were divided into 2 different groups respectively and wild soybeans were divided into 4 different groups.

UPGMA聚类分析结果表明，40份大豆材料聚为6类，育成品种和地方品种各自聚为一类，野生大豆聚为4类。

The results indicate that there exists more variation between landraces and introduced cultivars at least in phenotype level.

说明地方品种同引进品种和育成品种至少在表型上存在较大差异。

In the major progenitors in wheat breeding, the landraces showed distinct genetic difference.

2在我国小麦骨干亲本中，来自我国的地方品种与国外种质及包含国外种质的育成品种，具有明显的遗传差异。

Singer Leona Lewis and former Led Zeppelin guitarist Jimmy Page emerged as the bus transformed into a grass-covered carnival float, and the pair combined for a rendition of "Whole Lotta Love".

歌手leona刘易斯和前率领的飞艇的吉他手吉米页出现巴士转化为基层所涵盖的嘉年华花车，和一双合并为一移交&整个lotta爱&。

This is Kate, and that's Erin.

这是凯特，那个是爱朗。
